ELASTENG: COMPOUND.

Specification of Letters Patent.

Application tea August 12'. 1904. seritiueazines.

Be it known that L FREDERICK G. DoKKEN- WAIDEL, a citizen of the UnitedStates residing at Coshocton Ohio, have invented certain new and usefuiImprovements in Blasting (Compounds, of which the following is aspecification. V

The invention relates to biasting compounds and the method producing thesome.

The invention consists of quickly-huruing blasting compound and themethod. of producing the same.

I take of. sheets of paper, and preferably old newspapers, books.Wrapping-paper, and the like. and out the same into pieces, which areplaced in a vet. To sixteen pounds of shredded newspaper ladd about anequal' Weight of Water and also substantially about one-fourth theweight of silicate ofsoda. To

. this he added three-fourthsof a pound of glucose and, say, four ouncesof gins. if the powder is to he gram ,ed. The paper tmssoiution sometwelve to twentyfiour hours. The paper will then have assumed a. pulpyconsistency. Any excess water is then p'essed out, log the pulp dampand-siightly sticky. To forty pounds of the moist paper, thus saturatedwith silicate of sod sounds of nitrate of paiitssh. nitrate of soda, forshould-be stirred or coir? end is then pa and permit to hours in orderin oughiy puip being or at least a thorough iii'ture.

After the mass shali have become essimie one-third lated andsubstantially uniform it may be granulated by pressing throughperforated plates and then dryin and cuttinginto grains, or the mass maybe rolled or otherwise formed into sheets and dried at a temperature of180 to 220 Fahrenheit until all moisture is expelled. The sheets maythen be broken into lumps of convenient size. The granulation-is notconsidered necessar but adds to the appearance of the compound.

I do not confine myself to the precise proportions specified, but givethe above as a good practical working formula. The glue is unnecessaryif the material is not desired to be granulated. The color of thecompound is gray. v

As the chemicals are thoroughly incorporated with the pulp, it isbelieved the materials make a chemical combination of an unstatahlenature which explodes with force if ignited in a confined space.

What I claim is- 1. A blasting compound corc'r- .seu tially ofpepecpuip, mixed rates or soda and potash in excess of the (eight ofpaperpulp, and a quantity of so oughly incorp a 2. A d blasting compoundcomposed of pa pulp, nitrates of soda and potash fi'ieweight of the pulpend sulfur or out oiue-third of the weight of the pole and a eludingmixture of gin- (3"?9- and ail incorporated and formed into grainsuhstantiaily as described.

in testimony whereof l. afix my signature in presence of two Witnesses.
